re-tried my solo spirit deck (frodo/dunhere/eowyn) with the strategy of flying through questing and hoping nothing bad shows up- like you have a choice with this one....
actually went perfectly, 5 turns with no enemies and mainly low level locations, meant i flew through the stages hassle free....no damage....no increase in threat apart from the 4 per turn,
drew goblin sniper, dunhere dispatched him once then i used shadow of the past to put him back on, allowing me to throw every questing power i had into the quests while dunhere once again got rid of it.
in the end i had elfhelm/ eomund/ west road traveller/ riddermarks finest, and eoywn committed to questing, and used astonishing speed giving them all +2 will power, anways, my strategy worked, as there were no enemies in the staging area (admitedly through sheer luck), allowing me to finish stage 4b with a finishing threat of 44.
